Yes, some of the stuff being posted is over the top.
Quarantining “healthy people” and closing down schools is no longer just talk. Half or more of the 2500 passengers from the MS Grand Princess are probably healthy and not infected, yet they are quarantined. K-12 schools are closing when ordered, and hundreds of Colleges and Universities are going to remote lessons for the spring semester and possibly beyond. If public health officials determine someone needs to be quarantined, or a business closed, they will probably not have much say in the matter. That is just reality.
You're overstating that number as of today.
But in two weeks I'm betting it will be accurate.
